PROBLEM TO BE SOLVED: To provide a heat exchanger, a method of manufacturing the heat exchanger and a brazing tool, capable of manufacturing the high quality heat exchanger even if a core part is laid down and brazed and of enhancing flexibility of selection of a furnace used for the brazing. SOLUTION: The heat exchanger 1 includes the core part 4 in which a large number of tube elements 2 and fins 3 are alternately laminated, and the tube elements 2 of the core part 4 and the fins 3 are integrally brazed. The brazing tool 10 is inserted to the periphery of the core part 4, and notch parts 5 for tool insertion for preventing hanging and lamination shift of the core part 4 are provided.
